How to add a WEB API controller to an existing ASP NET MVC?

Question

API

There was a problem, everything worked, but after dividing the project into layers, going to api / st (st-name of the controller) shows that such a page was not found, but it should give the result of the getALL () method in XML format

Answer 1

There are (well, there should be) 2 files in the App_start folder - RouteConfig and WebApiConfig. Make sure all routes are properly defined and that your api/st is looking for the st controller, not the api controller c action-st. Nobody canceled the rule from particular to general.
